Hey all.
I was wondering if Ceph Octopus is capable of automating/managing snapshot
creation/retention and then replication? Ive seen some notes about it, but
can't seem to find anything solid.
Open to suggestions as well. Appreciate any input!

Care to provide anymore detail?

Does anyone else have any suggestions or options outside of a separate
dedicated OS? Seems like this should be something pretty simple and straight
forward that Ceph is missing.

Benji is independent from Ceph. It utilizes Ceph snapshots to do the backups,
but it has nothing to do with managing Ceph snapshots.
I am simply looking for the ability to manage Ceph snapshots. For example. Take
a snapshot every 30 minutes, keep 8 of those 30 minute snapshots.

I thought Octopus brought the new snapshot replication feature to the table?
Was there issues with it?

That is exactly what I am thinking. My mistake, I should have specified RBD.
Is snapshots scheduling/retention for RBD already in Octopus as well?

I have been doing some testing with RBD-Mirror Snapshots to a remote Ceph
cluster.
Does anyone know if the images on the remote cluster can be utilized in anyway?
Would love the ability to clone them, or even readonly would be nice.

Two separate 4 node clusters with 10 OSD's in each node. Micron 9300 NVMe's are
the OSD drives. Heavily based on the Micron/Supermicro white papers.
When I attempt to protect the snapshot on a remote image, it errors with read
only.

I have a rbd-mirror snapshot on 1 image that failed to replicate and now its

The cause of this was my fault based on my steps. Just trying to understand how

Decided to request a resync to see the results, I have a very aggressive
snapshot mirror schedule of 5 minutes, replication just keeps starting on the
latest snapshot before it finishes. Pretty sure this would just loop over and
over if I don't remove the schedule.

I have noticed that RBD-Mirror snapshot mode can only manage to take 1 snapshot
per second. For example I have 21 images in a single pool. When the schedule is
triggered it takes the mirror snapshot of each image 1 at a time. It doesn't
feel or look like a performance issue as the OSD's are Micr

Still interested to know if there are any options to make it so rbd-mirror can
take more than 1 mirror snap per second.

repeat what you are seeing and we do have test cases that really
hammer random IO on primary images, create snapshots, rinse-and-repeat
and they haven't turned up anything yet.
Thanks!

Any chance you can attempt to repeat the process on the latest master
or pacific branch clients (no need to upgrade the MONs/OSDs)?

This is a odd one. I don't hit it all the time so I don't think its expected
behavior.
Sometimes I have no issues enabling rbd-mirror snapshot mode on a rbd when its
in use by a KVM VM. Other times I hit the following error, the only way I can
get around it is to power down the KVM VM.

Isn't this somewhat reliant on the OSD type?
Redhat/Micron/Samsung/Supermicro have all put out white papers backing the idea
of 2 copies on NVMe's as safe for production.

I believe you partition the device, and then create your OSD pointing at a
partition.

nothing recent that addresses how the vendors are now pushing the idea of 2x.

All great input and points guys.
Helps me lean towards 3 copes a bit more.
I mean honestly NVMe cost per TB isn't that much more than SATA SSD now.
Somewhat surprised the salesmen aren't pitching 3x replication as it makes them
more money.

Looking at those articles they make me feel like the 40G they are talking about
